DRAWING-OFF noLL.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed November 29, 1907. Serial No. 404,429.

To all whom it may concern: I

Be it known that I, J OHN R. MILsoN, a citizen of the United States,residing at Watertown, in the county of Middlesex and State ofMassachusetts, have invented certain'new and useful Improvements inDrawing Off Rolls, of which the following is a specification, referencebeing had therein to the acoomlpanying drawing. 7

T is invention relates to drawing-off rolls for wool combs gill-boxes,and the like and the object of the invention is to provide a air ofrollsthat can be used without a eather apron to engage and draw off the woolfringe from the comb teeth without injuring the fiber, and pass the samein the form of a sliver through the trumpet to the coiler, or ballinghead.

It is found in practice that fluted drawingofi rolls always out the woolunless they have a leather or some yielding material between them to actas a cushion against which the wool is nipped. These leathers haveheretofore been made in the form of endless aprons which, owing to thesevere bendingstrains to which they are subjected in passing through thecorrugated rollers, soon wear out. Then again, the wear caused by theaction of drawing the fibers from the comb through the pins also assistsin destroying the apron, usually by wearing away the middle ortion ofthe same. These a rons are usua y of the very best quality of eather andare consequently very expensive, and as several of said aprons areemployed in each of the combing machines the expense of constantlyreplacing them to maintain the efficiency ofthe machine, isconsiderable.

By the use of my improved device a air of especially constructedcorrugated r0 s are' provided which effectually does away with theseleather aprons. These rolls are provided with teeth having pins soarranged as to engage the wool, draw it from the comb and pass itthrough the rolls. The nipping line between theteeth is provided with acushion or suitable flexible means to eflectually prevent the cutting ofthe fibers as they are nipped therein.

Heretofore where the aprons were used the fluted rolls were obliged tobe'madeof considerable size so as to prevent a too rapid cut-.

ting of said aprons, but by my improved construction the rolls may bemade much smaller allowing the nipping line of the rolls to be that'thesame are e ually brought much closer to the comb circles thereby drawingout more of the fibers, or saving more of the long stock, and leavinglesswaste or noils in the small circle.

Another feature of my im roved rolls is welhadapted to be used as thefront ro lers in a gill-box, where they are of great advantage, first,by doing away with the leather apron ordinarily used there, and second,that by being so much smaller the shorter fibers can reach the nipbefore the pins of the fallers are withdrawn from the sliver.

This invention consists of other novel features and arts andcombinations of the same as wil be fully described hereinafter and thenpointed out in the ap ended claims.

A practical embodiment of t e invention is represented in theaccompanying drawings,

forming a part of this specification, in which similar characters ofreference indicate corresponding parts in all the views.

In the drawings: Figure 1-is a central sectional elevation of a combshowing my improved drawing-OE rolls attached thereto. Fig. 2-is adiagrammatic plan view of the comb circles showing my improved rolls asa plied both to the larger circle and also to tffe smaller circle fordrawing the fringe therefrom and passing the same through the trumpet.to the coiler. Fig. 3shows the application of my improved rolls to agillbox. Fig. 4-is a side elevation of the corrugated binding roll. Fig.5-is a side elevation of the pin roll, the teeth of which latter rollare formed by a thin blade having a row of pins on each side thereof,and the space between said teeth being provided with a cushionedsurface. Fig. 6is a centralsectional side elevation of the pin roll.Fig. 7is a enlarged sectional end view of said pin roll. Fig. 8is asectional end view of the binding roll. Fig. 9is a perspective viewshowing both of the rolls together and the bearing for supporting thesame. Fig. l0is an end view of one of the bearings showing theadjustable spring tension on theboxes. Fig. 11 is avmodification showingthe 'pin roll as constructed with a row of short pins projecting fromthe edge ofeach tooth and a leather nip cushion of leather at-33 on theouter edge of the teeth of the binding roll 7. Fig. 13sh0ws a modifiedconstruction wherein the pins are removed from the drawing-01f rolls anda cushioning means is provided for both of said rolls.

Referring to, the drawings at 1 is the "frame of What is commonly knownas the Noble combing machine, in which the large comb circle isrepresented at 2 and the two small comb circles on either side at 3b.

The dabbing brushes, which strike stock down between the teeth of thecomh, are illustrated at 4 and 5, and my lll'lPlOVGLl drawing ofi rolls,which may he applied equally well to both the large and small. circles,are represented at 6 and 7. These drawing-off rolls are set on end andrun in pairs. The pin roll 6, which sets nearest to the approachingfringe to engage and draw it into the rolls, is mounted on the shaft 1 1and constructed as -follows: The middle portion of the roll is providedwith a shell or hub 9, which may be keyed or otherwise secured to saidshalt. Teeth are 'formed on this shell by blades 10-10 which rat-rteoutward at intervals all around the outer surface of said shell. Theseblades may be made separate and set into the shell or made mtegral wlththe shell, if desired. Pro ect 1 upward at close intervals all along onen'n r side of these blades 10 are the two rows of pins 11-11, theirupper ends being pointed and extending to substantially the same heightas the blades. At either end "1e middle portion of this roll are thenarro-.; corrugated driving gears 12 and 13, also connected to saidshaft 14. These gears for the purpose of meshing with similar gears onthe corresponding roll 7 to keep said rolls in time with each other.Outside of these gear are collars 15 15 also mounted on said shaft, andencircling these collars 15-15 are the retaining rings 16-16. Thesecollars and rings are for the pur of receiving the ends 01 the spring or{lea nip members 17 which are located bet. the blades 1010 and are forthe purpose of forming a cushion for receiving the pressure of the teethof the llinding roll to prevent the same from injuring the fibers of thewool as they are pulled or drawn from the comb pins through the rolls.it will seen that there is a space between the periphery o1 the collarand the inner circle of the rin whereby these spring or flexible nipmembers may slide when they yield and are elongated by the hi inpressure. At 18 and 19 at either end oi this roll are nuts adapted to bescrewed up on the threaded portion 20 of the shaft to hold all the men:-bers of this roll and lock the same in position.

A second or binding roll 7 is mounted on the upright shaft 23 the endsof said roll being provided with narrow gears 2 l24 which are adapted tomesh with the corresponding gears 12 and 13 on the opposite roll 6.These gears are held in position on said shalt by means of the threinledcollars 253 and Both cl s receive their motion through g ar The middle'oyided rvitl :1 eorrespendn J of ordwxwzrdly project-- 1 l H 1 ingteeth 2 ;-;l1iel1nieshwitli the pin 1' :ll and zile portion oi this rollare cut deeper than the teeth on the epposite roll, and ll s ol'1l1eteeth are also undercut er e111 14x1 3;, ell fer the purpose oi clearing1' points of the pins as the rolls revolve.

My improved rolls are practical in their construction and effective intheir operation and by their use combs and gill-boxes and analogousmachines to which these rolls may be applied may be operated at muchless expense, as the costly aprons are done away with and at the sametime a greater percentage of the long fiber is saved.
